A popular Chinese soup made with adzuki beans, sweetened with rock sugar and flavoured with tangerine peel.
Rinse the adzuki beans under running water, then drain and place in pressure cooker.
Break up the rock sugar into smaller pieces, then add to pressure cooker.
Add the dried tangerine peel, water and salt.
Cook in electric pressure cooker on "soup" setting for 28 - 32 minutes. (at 28 minutes the beans are cooked with a little bit of bite. Cook for longer if you enjoy your adzuki beans soft.)
After 28 minutes, release the pressure valve in accordance to your electric pressure cooker manual guidelines. If the the valve begins to bubble, then set the valve to natural release until done.
